2. INTRODUCTION, CUSTOM ASCII SERIAL PROTOCOL The Custom ASCII Protocol is a simple serial communications protocol which is optimized for use with our programmable digital panel meters, counters, timers and transmitters. Digital panel meters, counters and timers accept an optional serial communications plug-in board, which can be any of the following: • • • • • • • RS232 board RS485 board with dual RJ11 jacks.
USB connection of multiple meters to a PC can be via a USB hub or up to 5 hubs in series. Each USB connection is then automatically assigned a virtual com port number, which can be addressed via software. The USB standard specifies the maximum length of a USB cable as 5 meters (16 ft).

4. JUMPER SETTINGS & FIELD WIRING 1. SAFETY WARNINGS Digital panel meters, counters, timers and transmitters may be powered with AC (mains) from 85-264 Vac or 95-300 Vdc with standard high voltage power, or 12-34V ac or 10-48 Vdc with the low voltage power supply option. To avoid the possibility of electrical shock or damaging short circuits, always unplug the device before opening the case. Please refer to the respective device manuals for full safety information and instruction on how to open the case.

5. PROGRAMMING YOUR SERIAL DEVICE OVERVIEW Digital panel meters, counters, timers and transmitters are easily programmed via their serial port using Windows-based Instrument Setup (IS) software, which provides a graphical user interface and is available at no charge. This software allows uploading, editing, downloading and saving of setup data, execution of commands under computer control, listing, plotting and graphing of data, and computer prompted calibration.

7. CUSTOM ASCII COMMUNICATION PROTOCOL 7.1 SERIAL COMMUNICATION FORMAT The Custom ASCII serial communication format for RS232, RS485 and USB is the following: Duplex ...................... Full duplex for RS232 & RS485. Half duplex selectable for RS485. Baud Rate ................. 300, 600, 1200, 2400, 4800, 9600, 19200 selectable by front panel Menu item “Ser 1”, Sub-menu item “Digit 4” for DPM, "Digit 5" for counter. Parity ........................ None Word length .............. 8 data bits Stop bit ....
The Counter and Scale Meter are capable of supplying more than 1 measurement value (or “Item”) with each reading, as selected in “Ser 3”. In the counter, there can be up to 3 Items plus Peak and Valley values, depending on the selected Function. The scale meter can transmit Net, Gross and Peak weight. Values are transmitted in a continuous string with no space between them. If the 5th digit in “Ser 3” is set to 1, the termination characters of and optional appear after each value.
8. CONTINUOUS MODE 8.1 OVERVIEW In the Continuous Operating Mode, measurements are continuously transmitted by the meter or transmitter in a standard data format using printable ASCII characters at a user-selectable rate ranging from 50 or 60 Hz line frequency down to one measurement every 72 seconds. This data may be received by a remote display at a distant location, by a printer for data logging purposes, or by a host computer for data analysis or system control.

9. COMMAND MODE 9.1 OVERVIEW In the Command Mode, the device does not send any data automatically, but responds to commands received from a host computer. These commands can be: To transmit the latest, peak, or valley measurement. To reset the meter completely or just the peak and valley values and latched alarms. To display a value sent from the computer. To transmit present setup parameters. To receive new setup parameters. To monitor or alter data in selected memory locations of the meter.

CHARACTER 3: Command character: G F R Q X W Read bytes from RAM Memory Write bytes to RAM Memory (DPM and Scale meter only) Read bytes from Upper RAM Memory Write bytes to Upper RAM Memory Read words from Non-Volatile Memory Write words to Non-Volatile Memory CHARACTER 4: Number of bytes (G, F, R, Q) or words (X, W) Code # 1=1 2=2 3=3 4=4 5=5 6=6 7=7 8=8 9=9 A = 10 B = 11 C = 12 D = 13 E = 14 F = 15 G = 16 H = 17 I = 18 J = 19 K = 20 L = 21 M = 22 N = 23 O = 24 P = 25 Q = 26 R = 27 S = 28 T = 29 U = 30
The number of bytes n consists of a single code character representing values from 1 to 30 as shown above under CHARACTER 4. The most significant address aa consists of 2 hex characters as shown below under RAM MEMORY ADDRESSES AND DATA DEFINITIONS. GENERAL, READING AND WRITING NONVOLATILE MEMORY DATA Nonvolatile data is read and written as a continuous string of words consisting of 2 bytes or 4 hex characters (0-9,A-F) per word.
A total of 11 characters plus a CR must be included and sent as ASCII characters. Those in quotes below are included as shown. The other symbols represent a range of characters except for CR which is the ASCII character “0D”.
MODE 2: DPM with Signal Conditioner Card and in Remote Display Mode SETUP (left digit) = 1 Remote Display mode The baud rate must be set the same as the source which may be a PC Controller or another DPM. The format is the Slave Format. This is the same as MODE 1 above but without the Command Identifier “*”, the address #, and the Command letter “H”. This is the same format that data is transmitted from a DPM in the Continuous mode.
Remote Display Only – No Normal Readings 6 7 8 9 A B C Addressable remote display Single value remote display 1st value of value sequence 2nd value of value sequence 3rd value of value sequence 4th value of value sequence Programmed to select specific data from a data string Addressable Commands H, K or L commands 1 value only 1-4 sequential Values 2-4 sequential Values 3-4 sequential Values 4 sequential Values 1 value only The addressable commands of Modes 0-6 can display remote data on one or more Coun
Mode 7 is not addressable, and data representing a value to be displayed is received in a pointto-point connection. In addition to being displayed, that value is put into Item 3, where it may be selected for Alarm comparisons and/or for Analog Output. If a Coded Alarm character is included, it overrides the internal alarm comparisons. Modes 8-11 are able to extract one value of data from a sequence of values, and display that particular value only.
S = Sign of value, space (or +) for positive, - for negative value. Sign is optional in display modes 0-7, required in 8-11. D = Digit from 0 to 9. Number of digits may be 1-6 in display modes 0-7, but must be 6 in 8-11. P = Power of 10. 0-9, A-F where A-F represents 10-15 A = Optional Alarm Character as defined in section 2.1 = Carriage return character = Optional line feed character (ignored) These basic Command formats are used when the Remote Display Counter is in display modes 0 - 6.
